That increase in export revenue was because of higher fine and mid-micron wool prices, it said.
Strong-wool prices had remained low for several years and were virtually unchanged from the last year.
Positive consumer sentiment towards the sustainability of natural fibres was yet to drive a recovery in the strong-wool industry.
However, there were some indications that large manufacturers were starting to notice that shift in consumer preferences, the report said.
For example, furniture maker Ikea recently announced that, from 2025, all of its wool would be sourced sustainably.
If that was any indication of future trends, then there could be opportunities for strong wool prices to rise.
Competition from other natural fibres, such as cotton, and cheaper synthetic fibres remained a barrier for a sustained rise in strong-wool prices.
Unlike strong wool, fine wool continued to perform well but only made up a small proportion - less than 10 per cent - of New Zealand's total wool export volumes.
Because of comparatively high prices received for fine wool, those exports represented nearly 30 per cent of wool export revenue.
The current high price for fine wool was partially because of lower wool production in Australia, where merinos were the main breed, it said.
